I'm working on a new statistic called Longevity Index, that will hopefully be a bit easier to calculate than Crossover Strength. With this stat, I'm attempting to quantify (with a point value) how much longevity a song has had on a chart.

Can't you just look at how many days a song has been on a chart?
